Because of Xiahou Zheng's protection, the entire carriage team was intact, and after reorganizing the team, they continued to move forward, and soon left this scorched land.

A moment later, the group arrived at the foot of the lonely peak.

The royal city of the Qingling clan, Tyrese, is built on this lonely mountain, the height is nearly a thousand meters, the slope is extremely gentle, covering an area of more than ten square kilometers, looking up from the foot of the mountain, you can see a large number of buildings built on the mountain, endlessly, combined with the surrounding trees, a group of natural scenery, very distinctive.

The city of Tyrese has no walls, but at the foot of the mountain there is a tree wall of giant trees juxtaposed, and there are many lookout posts on the trees, and hundreds of skilled Qingling archers stand guard against them, who are the first line of defense in this tree city.

Through the tree wall through the middle gate, a stone-paved avenue winds its way to the top of the mountain.

On the side of the road, there are rows of strange and beautiful houses, all of which have one thing in common, that is, large trees are the main body, and the trees are built of stone and wood on the basis of the trees.

Xin sat on the carriage and admired this unique city.

The history of the Qingling clan is 60,000 years, and their technology is backward and their productivity is low, but their artistic and aesthetic development is not inferior to that of the Federation, or even higher. Hotels, courtyards, shops, each building here has been carefully designed by the builders, none of them are the same, each has its own wonderful, but maintains a high degree of consistency in the construction concept, every corner of the city, seems to have a special artistic beauty, people feel pleasing to the eye.

This is a city with a completely different style from the Federation, if you compare the technology content or comfort and convenience, Tyrese City will not be comparable to it in another thousand years, but if you compare it to artistic attainments or beauty, Tyrese is not worth it at all.

Tyrese is the largest gathering place of the Qingling Clan, with a population of more than 500,000, but in the eyes of everyone in the Federation, more than 500,000 is really too little, and it can't catch up with some slightly larger communities, not to mention the super cities on major planets, the number of people is calculated in the number of 100 million.

The carriage procession went all the way up the wide stone road, but there were not many Qingling people on the road, so they avoided it from a distance.

Xin Lin quietly released a telepathic probe and found that many Qingling people were hiding in the house, carefully watching the convoy from the crack in the door or the rooftop, and whispering to the friends around them.

"These people are the rumored Federation human ......"

"It's them, evil humans, who killed the great Silver Lake Priest as soon as they arrived!"

"That battle was terrible!"

"Why did the Queen bring them here?"

"I don't know, but the queen must be thinking about the whole family."

"Look, there are a lot of humans wearing metal armor, it's terrifying, I heard that many clansmen have been killed by these all-metal demons before."

Conversations like this took place between the Qingling people, and Xin Xiao listened secretly, only to know that the Qingling clan called the Space Marines all-metal demons.

Most of the Qingling people have a kind of inner fear of the Space Marines, one is because of the backward metallurgical technology, seeing that someone can wear a full set of metal armor, subconsciously raising the combat effectiveness of the Star Marine; The other is because there are too many terrible legends about space marines circulating in the Qingling Clan, which have left a lingering shadow in their hearts.

And the scene that happened in the forest just now, almost the entire Tyrese City saw it, the Silver Lake Priest died tragically under the laser cannon, which caused them a violent spiritual shock, and many people still had a trace of fear on their faces.

In addition, Xin Lin also found that the proportion of strong people in the Qingling clan is really high, and the Force warriors, that is, swordsmen, can be seen everywhere, and all of them are not weak, judging from the number of blades on their chests, most of the Qingling clan's people are swordsmen above the three leaves.

Occasionally, there are powerful swordsmen, swordsmen, and masters of the arts, who are bold, and stand on the side of the street to observe the convoy without disguise, with complicated expressions on their faces, some people are cold-eyed, some are curious, and some people are full of hatred in their eyes, and they cast a provocative look at the federal mission.

After the procession passed, the inhabitants of Tyrese City came out of their homes and watched from afar, pointing a few points.

Elanda looked back at the crowd behind her, and suddenly said loudly: "The fertility rate of the Qingling clan is really terrifyingly low, we have been in the city for so long, and we have seen less than ten children, what do they think, don't they pay attention to the population at all?" ”

"It's not that they don't want to give birth, it's that they can't." Xin Lin next to him shook his head and said, "The life span of the Qingling clan is extremely long, according to the federal chronology, they can live for an average of eight hundred years. With such a long life, there are no natural enemies, and there is no pressure to survive, so they have the habit of not being in a hurry to do anything, including having children, and the physiological structure of the Qingling clan is a bit special......"

Speaking of this, a strange smile appeared on Xin Lone's face.

"How special?" Elanda asked.

Xin Lin smiled and said in a low voice: "We human men and women will bring joy and happiness when they act together, but this is not the case with the Qingling clan, when they mate, it will be very painful, like torture, and the probability of a woman getting pregnant is very low, so, you know." ”

Elanda was stunned when she heard this, a flush flashed on her face, and she quickly reacted and asked curiously: "Xin Lian, how do you know these things?" ”

"There is information about the Qingling clan on the Internet, I have read it." Xin Silent replied half-truthfully, he didn't want people to know that he had mastered the language and writing of the Qingling clan for the time being.

"I see." Elanda nodded, and sighed again: "The talent of the Qingling Clan is outstanding, even if it is quite rare in the entire galaxy, but unfortunately the disadvantage of low fertility rate is too serious, if they had a population of more than one billion back then, even if the Federation has developed science and technology, and the overall strength is much higher than that of the Qingling Clan, it is not so easy to take down the Yixing Spirit." ”

Xin Xiao agrees in his heart, there are thousands of intelligent races in the galaxy, but if you want to gain a firm foothold in the interstellar world to compete with foreign races and expand your territory, the first condition is to have a huge population base!

It is an eternal truth that there is great strength in numbers.

With a huge population base, more strong people can be born, expand productivity, develop science and technology, conquer space, occupy planets, these are inseparable from human execution, the rumored civilization that replaces all activities with robots, does not exist in the galaxy, and this civilization is usually self-defeating.

The Federation has a population of more than 600 billion, which seems to be many, but in fact it is only a drop in the bucket in the galaxy, not to mention the far, the steel-maned empire that is close at hand has more population, and the Federation has no exact data, but it is expected to be more than one trillion!

The low fertility rate of the Qingling people is actually a very easy problem to solve.

The women of the federation no longer have to get pregnant and give birth to children by themselves, each baby is bred in the nutrition tank, there is no impact on the mother, the technology is very mature, if the federation is willing to provide technical support, the population problem of the Qingling clan will be solved immediately.

"But why would the Federation do that?"

Xin Lonely laughed, believing that the upper echelons of the Federation would consider this matter thoroughly, and it would not be their turn to worry about it.
